MARVEL-MAGNETO, the most compact UUV detecting magnetic anomalies

MARVEL-MAGNETO

MARVEL-MAGNETO

MARVEL-MAGNETO AUV just make AUV technology accessible. Using MARVEL-MAGNETO is certainly nowadays one of the most simple and cost-effective way to detect magnetic anomalies.

Equipped with a fluxgate magnetometer sensor from Sensys MARVEL-MAGNETO provide with a great quality of image with high-stability, accurate navigation and capable of managing coastal areas with waves and current.

MARVEL-MAGNETO is equipped with underwater acoustic positioning and communication module.

With an autonomy up to 8 hours, and speed up to 6knots, and depth rated at 300m.

Thanks to the INX navigation, DVL and acoustic positioning, MARVEL-MAGNETO is able to have a navigation accuracy equal to <5m absolute positioning within USBL surface module range.

SEAPLAN software provides an ideal and versatile interface for the MARVEL-MAGNETO AUV and have pre-defined lawn-mover patterns to make a swift scan mission.

Thanks to its mission programming savings and updates, SEAPLAN facilitates discovery of new area as well as repetitive mission in similar locations.

MARVEL-MAGNETO is provided with all the necessary functions to be ready-to-deploy :

  • INX Navigation system
  • DVL
  • SEAPLAN Software
  • Embedded rechargeable batteries
  • SEACOMM
  • Field case and accessories
  • Acoustic positioning and communication module
  • Autonomous buoy with USBL unit and dual antenna GNSS-RTK module

*MARVEL AUV is subject to dual use export license from SBDU authority in France.
